Abstract
The utility model relates to a 220KV isolating switch electrification direct-connection short jumper device consisting of a main rod, an isolating rod, a connecting line and a wire clamp, wherein the main rod is an expandable structure and is provided with a fixation clamp for fixing the insulating rod; the end of the main rod is provided with an O-shaped ring for fixing a cable loop; the insulating rod is positioned at the external part of a screw rod with threads and is matched with the screw rod, and the external end of the insulating rod is provided with a hand shank; and one end of the screw rod is provided with an adjustable part of the wire clamp. Compared with the prior art, the device has the advantages of reasonable configuration, reduced number of operating people, reduced working time and the capability of leading contact surfaces between the wire clamp and a lead to be tightly connected with each other.
Description
Technical field
The utility model relates to the device of the charged direct connection shorting stub of a kind of 220KV of being used for isolating switch.
Background technology
In the traditional work, the charged direct connection shorting stub of 220KV isolating switch device is because defective such as the restriction of its structure exists operation dumb, and the activity duration is long, and wire clamp and lead contact-making surface tightness are not enough.The problem of above-mentioned existence will be brought problems such as the operating personnel increases, operating time prolongation to the charged direct connection shorting stub of isolating switch work, be a no small hidden danger during power system security is produced.
Summary of the invention
The purpose of this utility model is by innovation, provides a kind of rational in infrastructure, can shorten the operation number, shortens working hours, and can make wire clamp contact the device of the charged direct connection shorting stub of 220KV isolating switch closely with the lead contact-making surface.
For achieving the above object, the utility model is achieved through the following technical solutions:
The charged direct connection shorting stub of 220KV isolating switch device is made of mobile jib, insulating bar, connecting line, wire clamp, and mobile jib is a Collapsible structure.
On mobile jib, be provided with the geometrical clamp of fixed insulation bar; Be provided with the fixedly O type ring of sling in the mobile jib end; Insulating bar is positioned at threaded leading screw outside and matches with leading screw, and the insulating bar outer end is provided with handle; One end of leading screw is provided with the variable partition of wire clamp.
Compared with prior art, the utility model has the advantages that:
Rational in infrastructure, can shorten the operation number, shorten working hours, and wire clamp is contacted closely with the lead contact-making surface.
Description of drawings
Fig. 1 is the structural representation of this device.
Embodiment
The charged direct connection shorting stub of 220KV isolating switch device is made of mobile jib 1, insulating bar 2, connecting line 3, wire clamp 4, and mobile jib 1 is a Collapsible structure, is convenient for carrying, and promotes operation.On mobile jib 1, be provided with the geometrical clamp 5 of fixed insulation bar 2, when promoting, insulating bar 2 be positioned over geometrical clamp 5 internal fixation, be convenient to operation.
Be provided with O type ring 6 in mobile jib 1 end, this structure is used for the usefulness of rope-tying buckle; Insulating bar 2 is positioned at threaded leading screw 7 outsides and matches with leading screw 7, and insulating bar 2 outer ends are provided with handle 8; One end of leading screw 7 is provided with the variable partition 9 of wire clamp.By shaking of handle 8, can make insulating bar 2 drive leading screws 7 and move forward, the variable partition 9 that drives wire clamp inwardly moves, and makes wire clamp 4 can closely fix contact-making surface with lead.
